1. A segment routing header compression method, comprising:
configuring a regular compression segment identification for respective nodes on a segment routing path and configuring an extended compression segment identification for at least one of nodes on the segment routing path, the extended compression segment identification of the at least one of the nodes comprising at least a function field;
generating a segment list, the segment list comprising the regular compression segment identification of the respective nodes and the extended compression segment identification of the at least one of the nodes, wherein in the segment list, the extended compression segment identification of the at least one of the nodes is adjacent to and located behind the regular compression segment identification of the at least one of the nodes; and
carrying the segment list in a segment routing header of a service message.
